Why do people say they are bi but?

That makes me so angry. As a biual man, it was extremely tough for me to accept myself and go through the hle of coming out. Yet these young people say things about themselves to make them more attractive to men who have fantasies of two girls going at it. That's my problem. Their not bi, but they are saying it to appear more ually appealing. To me, it just makes me think they are wh0res. It makes true people look like fakers and addicts, when that is not true at all.
